Prevalence and Practice Domains of Advanced Practice Nurses Among Participants in the Latin American Nursing Leadership School: A Cross-Sectional Study

<b>Aims:</b> This study aimed to determine the prevalence of nurses in a Latin American leadership school who meet advanced nurse standards. <b>Design:</b> A descriptive cross-sectional study was conducted. <b>Methods:</b> Data were collected between January and November 2024 from a total of 92 participants from the Latin American Leadership School of FUDEN-FEPPEN (Foundation for the Development of Nursing-Pan American Federation of Professional Nurses). The response rate was 13%. The Spanish version of the APRD (advance practice role delineation) was validated in Spanish. The study was approved by the Social Ethics Committee of UCLM (Universidad Castilla-La Mancha). Inference analysis was performed to examine factors associated with advanced practice domains. <b>Results:</b> A total of 92 nurses participated in the study. Among the participants, 35.86% (33 nurses) met the requirements for advanced practice nurses and the minimum training required by the International Council of Nurses. Nurses in both primary care and specialized care perform more advanced practice activities in direct care; however, nurses practicing teaching and research perform more advanced practice activities in the indirect practice domains (training, research and teaching). <b>Conclusions:</b> The percentage of nurses participating in the Latin American leadership school who met the standards was determined, with the most frequent domains those related to direct care, such as expert care planning, integrated care, and inter-professional collaboration. <b>Implications for the profession and patient care:</b> To our knowledge, this is the first study that describes the profile of advanced practice nurses in the Latin American context. This study shows that advanced practice activities exist and are practiced, but there is no clear delimitation or regulation of these activities. <b>Reporting method:</b> The study was conducted following the STROBE guidelines. <b>Public contribution:</b> This study did not include patient or public involvement in its design, conduct, or reporting.
